Is Taco seasoning Keto?
Taco seasoning is a mix of spices and herbs that make Mexican food delicious. But many taco seasonings contain ingredients that are not keto-friendly like brown sugar, soybean oil, and corn starch.
If you are on a keto diet, you have to be careful about what taco seasoning you use because most have ingredients which will kick you out of ketosis.
Luckily, you can now purchase keto taco seasoning, which is also sugar free, zero calorie and low sodium. I can’t live without this one!!
Do you cook chicken before putting it in a casserole?
There is no need to pre-cook the chicken before putting it into the casserole with this recipe. You can use raw chicken and it will cook as the casserole cooks.
If you want to speed up the time it takes to make this chicken fajita bake recipe then you can precook the chicken on a pan or just use chicken that’s already been cooked.
I often use leftover shredded rotisserie chicken in this recipe. If doing so, reduce the baking time to 20-25 minutes.
What You Need to Make Keto Chicken Fajita Casserole:
- 1 pound of raw skinless chicken breast
- 2 medium sized bell peppers, seeded and cut into cubes
- 1 small onion cut into slices
- 1 1/2 tbsp taco seasoning
- 1 8 oz package of cream cheese at room temp
- 1 can of tomatoes

Can you make ahead chicken fajita casserole with cream cheese?
You can bake this casserole ahead of time and reheat it for when you are ready to eat.
It’s best to reheat it in the oven by cooking for 15-20 minutes at 300F (150C) to warm the casserole up.
Alternatively, you can reheat single portions in the microwave.
Substitutions for chicken fajita casserole with rice
If you’re following the ketogenic diet you can’t have regular rice. A good substitute is cauliflower rice.
If you’re not a fan of chicken, you can use ground beef.
